Colossus, arguably the first digital computer, was created at Bletchley Park during WWII. In keeping with the spirit of this, we are inviting everyone to bring along items of old computing capability. If you have any old bits of computer equipment (early PCs, adding machines) or related relics (log tables, sliderules, magnetic tape, punched cards, etc) hidden away in your attic or garage, please bring them along. There will be a small display area where everyone will be able to view and discuss these items during the day.
